What percent of 177.7 is 33.9? ? explain

Let's try a sample question.
What percent of 200 is 100?
We can find our answer like so:
200x = 100
Divide each side by 200.
x = 100/200 = 50/100 = 50% (a percent is literally just a fraction out of 100)

Now let's look at the question:
What percent of 177.7 is 33.9?
177.7x = 33.9
Divide each side by 177.7.
x = 33.9/177.7 ≈ 0.19077 = 19.077% (multiply decimal by 100, add % sign)

2xy/9 is the answer to this problem
